Fix -Wunused-but-set-variable compiler warnings in tevent_signal.c
The results of some read(2) and write(2) calls are assigned into a
variable that is never used. Presumably this used to avoid compiler
warnings or similar.
However, from (approximately) GCC 4.6 this produces some warnings:
[ 609/3910] Compiling lib/tevent/tevent_signal.c
../lib/tevent/tevent_signal.c: In function ‘tevent_common_signal_handler’:
../lib/tevent/tevent_signal.c:85:10: warning: variable ‘res’ set but not used [-Wunused-but-set-variable]
../lib/tevent/tevent_signal.c: In function ‘signal_pipe_handler’:
../lib/tevent/tevent_signal.c:183:10: warning: variable ‘res’ set but not used [-Wunused-but-set-variable]
The simplest thing to do is remove the variables and cast the function
return to void. There is already a comment above each call.
